Walnut (Juglans) is born from the Juglans plant that belongs to the Family of Juglandaceae.

The plant can reach 15 meters high and 8 meters wide.

Walnut has a significant presence of components beneficial for human health, including fats, vitamins and proteins, including :

  • omega3 fats
  • omega6 fats
  • alpha-linoleic acid
  • vitamin B1
  • vitamin B2
  • Vitamin B6
  • vitamin E
  • polyphenols

All these substances effectively combat the high levels of harmful LDL cholesterol and promote the proper performance of the cardiovascular system (1).

Recent studies in the US have found that a daily intake of 3-4 nuts contributes to the human body, about :

  • 5 grams of fiber
  • 250 mg potassium
  • 70 mg calcium
  • 90 mg magnesium
  • 3.5 mg vitamin E
  • 150 mg sodium


Which benefits not only the cardiovascular system, but also the immune system.

Walnut has antioxidant, anti-inflammatory, antimicrobial and antifungal activities due in large part to the significant content of alpha-tocopherol (a compound of vitamin E), flavonoids, phenols, alkaloids, terpenoids, tannins, saponins and steroids (2).

Walnuts are an excellent source of vitamin E and magnesium. People who consume 3 nuts take folate, beta-carotene, vitamin K, lutein, zeaxantine, phosphorus, copper, selenium, potassium and zinc for about 1000 kcal (3).

This animal study supports the hypothesis that daily consumption of walnuts could suppress the growth and survival of breast cancer (4).

However, care should be taken to purchase bleached walnuts, as chemicals may be used in the bleaching process.

The walnut, collected from the tree or from the ground, should only be cleaned with a toothbrush to remove any incrustations of soil or parts of the hull.

The hull is used as a natural black dye and as a hair dye.

Furniture is made from high-quality walnut wood.
